Persistently dry skin is supported by omega-3, vitamin D, and vitamin C; these support the skin barrier and collagen it depends on.

Omega-3 fats are part of the skin's barrier that holds water in, so a low intake is linked to dryness and inflammation. Vitamin C is required to build collagen, and low vitamin D is associated with several skin conditions, while collagen peptides support the skin matrix over weeks.
